IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 122,093, dated December19, 1871.

To all whom t may concern:

Be it known that I, JOSEPH B. WILSON, of Philadelphia, county ofPhiladelphia and State of Pennsylvania, have invented an ImprovedWashing-Machine, of which the following is a specication:

My invention consists of a Washing-machine too fully described hereafterto need preliminary explanation 5 the said machine having been es'-pecially designed With the view of cleaning dirty cotton-Waste, greasyrags, &c.

Figure l is a vertical section of my improved Washing-machine; Fig. 2, aside view partly in section; Fig. 3, a sectional plan 5 and Fig. 4, aside view of one of the cog-Wheels.

A is an annular trough formed by an outerllange, a, and an inner flange,a', on the base b.

The lower end of a vertical shaft, B, turns in the center of the base b,and the upper end in any suitable frame, or in the joists and beams ofthe oor above that on which the machine rests, the shaft being driven bya belt or any suitable system of gearing. Through a transverse slot inthe shaft B passes a plate, d, secured to a bar, D', on the end of whichthe cog-Wheel E revolves freely, the plate being bent at the end so asto prevent the 4bar from moving radially from the shaft, and the wheelbeing maintained in one position horizontally on the bar by collars,pins, or i otherwise. A like plate, d', passes through the slot of theshaft, this plate being secured to a bar, D', on Which turns thecog-Wheel E. The

Wheels E and E are arranged at such a-distance from the shaft that theouter edge of the periphery of the Wheel E will traverse in an annularcourse at or near the inside of the outer flange a. of the trough, Whilethe inner edge of the Wheel E Will traverse at or near theilange a,'andthe Wheels are of such a Width that the annular course traversed overthe bottom of the trough by one Wheel will overlap that pursued by theotherwheel, as best observed by referring to the dotted lines in Fig. 3.The slot in the shaft B is so elongated vertically that the Wheels areat liberty to rise or fall and accommodate themselves to the thicknessof the malterial in the trough.

Dirty Waste, such as is useless for further cleansing purposes inmachine-shops, grease-rags, or any other fibrous or textile materialwhich it is desirable to Wash, is deposited in the trough with thewashing-fluid, and the shaft, with its cog-Wheels, is caused to revolvein contact with the mass. The Weight of the Wheels causes the teeth ofthe same to act on the material With a kneadin g effect, which, aided bythe liquid, forces thegrease, dirt, 85e, from the fibers of the fabric,every part of the mass in the trough being ex- In testimony whereof Ihave signed my name to this specification the presence of two sub`scribing witnesses.
